There are no cranial chai'acters of any importance, except size, 
by which the skulls oi si/lvaticus, floridaiius, and mearnsi can be 
separated; mearnsi is larger and floridanus smaller than 
syhmticus. There are one or two slight differences, that seem to 
be fairly constant, by which the skulls of tramitionalis can be 
distinguished from those of sylvaticus. 
The skull of transitionalis averages shorter and broader, with 
the nasal bones shorter and broader than in sylvaticus. The 
postorbital process of the frontal bone also is slender and short, 
and seldom joins the skull posteriorly, and when it does, only 
by the extreme tip, always leaving an open foramen between it 
and the frontal bone. 
The postorbital process in syloaticus is broad and heavy and 
often, in old examples, fused with the frontal bone, with" little, 
sometimes no, open space between. 
The incisive foramen is of a slightly diffei-ent shape. In 
sylvaticus the two outer sides taper to a point just back of the 
incisors, leaving a cone-shaped opening. In transitionalis the 
two outer sides extend parallel for about two thirds the length of 
the opening, then suddenly turn in towards each other, m'aking 
two decided shoulders, and then continue up to the end just back 
of the incisors, thus leaving a bottle-shaped opening.
